Abstract: (2666 Views)
Irregular use of chemical fertilizers and lack of attention to the importance and positive effects of organic materials in improving the fertility of agricultural soils have been resulted in environmental pollution and ecological damage. Therefore, biological resources should be used to reduce these risks to increase the availability of nutritional elements to improve the physical and microbial conditions of the soil. One of the biological resources is marine algae which are rich in materials needed for plant growth. In this study, the effect of alga (Ulva fasciataL.) extract has been investigated on some physiological parameters of Sesamum indicumL.The experiment was conducted using randomized complete block design with 4 replications by different concentrations of alga extracts (0, 10, 15, 20 %) in field condition in the city of Iranshahr. According to the results, morphological traits including radicle length, hypocotyl length, stem length stem diameter, and leaf area increased compared to the control significantly. Also, photosynthetic pigments increased compared to the control significantly, so that the highest content was observed by 20% alga extract. Highest content of prolin (16 mg/g F.W), soluble sugars (54 mg/g F.W) and phenol (3.8 mg/g F.W) was observed by 20% alga extract. Generally, alga extract with having essential plant elements and growth hormones, without damage to nature as a bio-fertilizer can be a good alternative to chemical fertilizers and can have an important role in managing the supply of healthy food.
